Optimized Airflow

To validate its form through function; Unitronic engineers strategically used CFD to maximize the efficiency of this Intake System. After countless hours of test fitments and product validations through several iterations, the result is a design that maximizes the room available in the engine bay while exhibiting smooth volumetric transitions where every facet is effectively executed for form and function.

Proven Airflow Gains

Unitronic Hardware Engineers carefully benchmarked the OEM Audi S4 / S5 turbo inlet versus the Unitronic Turbo Inlet in a controlled environment using our in-house Superflow SF-1020 flow bench. Our team observed massive air flow gains of up to 57% with the Unitronic Intake and Turbo Inlet. This drastic air flow improvement allows the turbochargers to work more efficiently and achieve target boost with less stress resulting in improved reliability.
